svetoff [14.1K]

Answer:

Step-by-step explanation:

50 employees make up the sales team, 25 male and 25 female, 5 choice leads are assigned

a)

p(first lead given to male)=25/50

p(second lead given to male)=24/49

Since the probabilities of first and second are not affected by each other, the events are independent

b)

Given that first four leads go to men

Therefore, number of men left=21

number of employees left=46

p(fifth lead goes to man)=21/46

c)

At least four leads go to man, given

four leads are men

number of men left = 21

number of women left= 25

number of employes left = 46

probability= \frac{^25C_5(all.5.men)}{^25C_5(all.5.men)+^25C_4(men)\imes ^25C_1(woman)}\\\\=\frac{21}{146}

xz_007 [3.2K]

9514 1404 393

Answer:

  5 seconds

Step-by-step explanation:

Suppose the front parts of the trains meet at point A. Since both are the same length and traveling the same speed, each will pass point A in time ...

  time = distance/speed

  time = (1/18 mi)/(40 mi/h) = (1/720 h) × (3600 s)/(1 h) = 5 s

That is, the rear part of each train will be at point A 5 seconds after the front part.

The rear parts will pass each other 5 seconds after the front parts meet.
